Detailed description of the invention
Gate pier is xoncrete structure, or reinforced concrete structure, or stone masonry structure etc., can guarantee that the dutiful work of gate pier
For foundation；Gate floor is reinforced concrete structure, or xoncrete structure, or stone masonry structure etc., also can guarantee that gate pier is dutiful
Work is foundation；Both sides gate pier and gate floor cast in situs, and water and build up a complete overall structure, stable to increase it
Property；Gate pier height should be greater than or equal gate height, to ensure that safe operation is as foundation；Gate axle uses rustless steel or alloy etc.
Material, and be fixed on gate pier by bearing, gate axle requires there are enough strength and stiffness, it is ensured that gate axle does not produce any
Deformation；Hollow gate is the material such as cast steel or steel alloy, should have certain rigidity and intensity, carries out antirust treatment, hollow gate
Inside it is provided with vertical and horizontal dividing plate, to increase rigidity and the intensity of hollow gate.Bearing visual stress size uses the axis of rolling
Hold or sliding bearing or use hinged bearing, make hollow gate freely to rotate around gate axle, and carry out water-proofing treatment；Upper gear
Block, lower block should pour into an overall structure, and proof strength requirement with gate pier；Between hollow gate and upper and lower block,
It is provided with bar shaped sealing between hollow gate and gate floor, between gate and the gate pier of gate axle surrounding, is provided with "○" type
Sealing collar, produces during to prevent hollow closing gate and leaks, it is ensured that normal water-retention.
When the present invention works, after upland water amount changes, make water level change, do so and be used on hollow gate
Water pressure also can change therewith, and hollow gate, can be automatic in upper water pressure and hollow gate under the common effect of water gravity
Complete the opening and closing process of hollow gate:
When the upstream water yield is relatively low, now needing water-retention of closing the door, owing to its water level is certain value, the water at water source, upstream can lead to
Crossing inlet opening and be freely accessible to hollow gate, in it, air is discharged by draining (gas) hole, the water level in hollow gate and water source, upstream
Water level is contour；Due to hollow gate under-filled certain water yield, cause the gross weight of hollow gate bottom more than top
Weight, therefore, the anticlockwise moment that gate axle is produced by bottom gate and water is more than the side clockwise of the generation on top
To moment, hollow gate is closed mode, beneficially water-retention.
If upland water amount increases, water level raises, and due to the effect of inlet opening, makes the water level in hollow gate also rise to
The water level identical with upstream water level, the portion gas in hollow gate is discharged by aerofluxus (water) hole；When upper pond level is with empty
When heart gate door top is contour or is higher than hollow gate lock top, equally, by the effect of inlet opening, in hollow gate can be made, it is full of water,
Gas is all discharged, and the unnecessary water yield entering gate also can pass through the discharge of aerofluxus (water) hole, can be always maintained in hollow gate
It is filled with water；The water yield so making hollow gate axle top increases to maximum, utilizes this part water weight, increase accordingly gate
The weight of the hollow gate in axle top, is more beneficial for the unlatching of gate.Now, the moment that gate axle is produced by gate top, bottom
Difference just become one quantitatively, afterwards, the rotation of hollow gate is then controlled by the water pressure of hollow gate upstream and downstream completely；Along with
Upland water amount increases further, and when water level before gates is increased to certain altitude, at hollow gate, in it, water weighs and upper water pressure
Under common effect so that the moment (around the moment of gate axle) acting on hollow gate top is more than the moment of bottom (around gate
The moment of axle), hollow gate can be made to turn clockwise, hollow gate automatically opens up, and upland water can pass through hollow gate and lock
Channel downstream between base plate and above hollow gate top sluices；When upland water amount maintain a certain amount of no longer change time, empty
Heart gate letdown flow is equal with upland water amount, and before hollow gate, water level keeps stable, and the aperture of the most hollow gate keeps steady
Fixed；If upland water amount increases further, before the most hollow gate, water level raises further, acts on the power on hollow gate top
Square increases further with the torque difference of bottom, and the aperture of hollow gate can increase further, makes letdown flow increase further, if
When upland water amount increase to a certain amount of no longer change time, before hollow gate, water level keeps stable, hollow gate letdown flow with
Upland water amount is equal, and the aperture of the most hollow gate keeps stable；When come the water yield increase to a certain degree, water level before hollow gate
After rising to certain altitude, hollow gate can be fully open, now, and hollow gate and the bottom of upper block and the top of lower block
Portion contacts, and hollow gatage reaches maximum, makes discharge capacity reach maximum, to complete the needs of flood discharge well.
When upland water amount reduces, before hollow gate, water level can decline therewith, water weight in gate axle top weight, gate
And the torque difference of the upper water pressure moment and bottom that act on gate axle is also gradually reduced, the aperture of hollow gate is made to reduce,
Letdown flow reduces；When upper pond level reduces further, act on the hollow moment on gate top and enter with the torque difference of bottom
One step reduces so that gate rotates towards the direction of current upstream automatically, and the aperture of the most hollow gate can automatically reduce, thus subtract
Little letdown flow；If when upland water amount be reduced to a certain amount of no longer change time, before the most hollow gate, water level keeps stable, hollow
Gate letdown flow is equal with upland water amount, and keeps constant, and the aperture of the most hollow gate keeps stable；If upper pond level
Further reduction, when less than hollow gate door top, the water level in hollow gate declines the most therewith, the water on hollow gate top
Heavily reducing, cause and act on the hollow moment on gate top and quickly reduce with the torque difference of bottom, gatage reduces further；
When upland water amount is reduced to a certain degree, before hollow gate water level decreasing to a certain extent time, then by gate axle bottom weight
Amount, water weight and upper water pressure act on the moment of gate axle and can make the aperture of hollow gate more than the moment on top in gate
Reducing, until completely closing, completing the task that automatic barrier gate stores.
When after hollow closing gate, owing to being all provided with between hollow gate and both sides gate pier, gate floor and upper and lower block
It is equipped with sealing, hollow gate can be kept water-tight.Can preferably retain the water-retention of hollow gate upstream, in order to Xing Li makes
